renew domain registration

Hello, I had the domain: lillungallad.com until the september 28, but I wasn’t here to renew it in time and someone of my family, an evangelic who think that what I do is evil, hack my codes to supress it. I’d like to renew my domain, but I had read that it will be very expensive. It is not my fault if I didn’t renew it in time, so, what can we do? Lillungallad is a word I have created, it is mine and protected in France by the state, and I will be very depressed if someone take it. I’d like very much to renew it with the normal price, because I’m kind of poor actually, I have lost my job. I hope you will understand and I’m sorry for the bad english.
